In people's lives, there have been unforgettable things.

Those treasures that come from life cannot be parted with no matter what.

From the first time I met Shiro, the feeling of faint pain in Yili's heart gushed out like a flood that opened the floodgates.

A sense of déjà vu, a fit of soul.

However, in his memory, no matter how he retrieved it, there was no presence of her.

The girl who suddenly appeared in front of him.

Huge labyrinths, mysterious rivers...... Where is this place, where is he going, where is he coming from, and where is it all going to be?

Mysteries haunted him.

Fragments of memory are hiding in the story, waiting for him.

[After a person is injured, he often hopes that the things he relies on and loves will heal the pain. 】

[You say, will I be your favorite?] 】

The girl said.

The infinite truth hidden in the spiral of the book will only converge in one direction in the end—that is, the heart.

......

The sound of ticking resounded, but he could only feel his heavy body, as if he had been pressed to the bottom of the sea by a thousand pounds of boulders, allowing himself to continue to fall in this mysterious sea.

Yili, who came to his senses, opened his eyes slightly, but unconsciously opened his mouth slightly, and the raging sea water desperately drilled into his mouth, and he was scared in the next second, he reached out and tightly covered his mouth and nose.

The feeling of choking on water is so uncomfortable. Strangely, the water here actually smells of medicine.

He looked around, and he had to find a way to get out of here quickly.

He looked into the depths of the sea, a place comparable to a black hole, but he vaguely felt in his heart that the way out was in a place where there seemed to be no escape.

So he went down as fast as he could. It's a bet he makes with himself.

But his strength was completely insufficient. Just getting a little closer down, it took all the strength of his body.

At this desperate moment, when he was about to drown, he exaggerated the feeling that in addition to the smell of medicine, there was also a kind of emotion that made people can't help but be sad swimming in it.

At this moment, several transparent hands came straight to Yili from the bottomless darkness, like swimming dragons. They grabbed him by the wrist and dragged him deep in.

Barely conscious, he watched himself fall into the darkness like this.

But when he pierced through the darkness, it was as if his feet were glued to the land, stepping on something and no longer moving, his transparent hand lifted his body, and the water droplets carried on his body fell back into the river with the transparent hand, and he just stood up.

The suffocating feeling was swept away by the smell of damp grass here for a moment, and Yili, who was relieved, enjoyed the fruits of his winnings - the silver river that brought him out, and the black mist of the grass with his vast body domineeringly. Ethereal, unpredictable, and easy to get lost. Here, he doesn't really see it.

The black mist is like an ugly beast guarding its territory, and it has been hovering here without any intention of dispersing.

The huge space, but he was alone, the unspeakable fear and loneliness in his heart overflowed his heart, and the black fog here seemed to have self-consciousness in his eyes, looking at him with the mean eyes that he thought in his heart.

Yili didn't want to endure all this anymore, but in this strange and terrifying environment, he could only choose to hide in the light of the river to dispel the black fog, close his eyes, and quietly wait for the fear to dissipate.

Don't be afraid. 】

Suddenly hearing the voice, Yili lifted his head from the crook of his arm, which was the little haven he had built for himself.

On the other side of the river, a girl stood at some point.

Yili looked at her and saw the indifferent smile on her face, like a refreshing cool breeze in summer and autumn, dispelling Yili's uneasy worries.

"It's not going to help sitting there all the time, is it? It is better to cross the river and come to my side. The girl's voice was very soft, and it sounded innocent, and even the somewhat autistic Yili couldn't help but let down her guard and believe her.

Yili stood by the river, looked at the river that was not shallow, looked at the trousers he was wearing, and hesitated.

"Don't worry, come here." The girl held out her hand to him.

Yili exhaled, as if mentally prepared, wading across the river and grabbing the girl's hand.

After crossing the river, which was not deep, he lifted his feet, but found that his trouser legs were not wet, and he had just come out of the river, and there were no signs of wetting the clothes on his body.

"Like a source of inspiration, abstract things don't directly interfere with the real thing." His eyes were drawn to her tightly, as if he could no longer take his eyes off, the pure white dress swayed slightly in front of his eyes, and the beautiful hair was draped over his shoulders, but it was the long white hair he had never seen before.

He looked at the girl, and a familiar feeling appeared in his heart inexplicably, as if he was familiar, but his mind was blank and he couldn't think of anything.

"My name is Shiro." The petite girl in front of her was the first to introduce herself. "As a courtesy, can you introduce yourself to me as well?"

Yili hesitated for a moment, but still spoke obediently: "My name is ...... Yili. ”

Zhibai's smile seemed to be even bigger.

"I guess there must be a lot of problems in your self-enclosed heart." Zhibai put his finger on his chin and deliberately pretended to think.

Then, she spread out her hand again and said in a very helpless tone: "But unfortunately, I don't know much about it." ”

"But I can feel that I belong here, so even if I don't know it, I know how to understand it all."

Zhibai turned sideways slightly, stretched out his hand and pointed in the direction of the river's slow progress.

"Follow me."

In the chilling black mist, this shimmering silver river is undoubtedly the only guide to dispel the black fog.

Yili quietly followed Shiro, who led him forward, without saying a word.

"Don't act so rusty, just treat me as your friend."

The mysterious white leaned up to his face and posed a "one" to him with his index finger: "You have to remember, I am your first friend now." ”

Hearing this, he lifted his head and met her sincere eyes.

The eyelashes that fanned like feathers and the clear eyes that were like rivers were the same color as his hair colored, and the gray in his eyes seemed to be completely opposites.

He didn't understand where he was, he couldn't think of anything about his past, and he couldn't retrieve any impressions of her......

Will they be people with whom they have a good relationship?

"Well, you have amnesia. I should have noticed it. ”

Yili was a little surprised, did she answer her own thoughts?

"Yes, it's not just thoughts...... "Zhibai turned his head away from him, and walked on his own. You can also feel your mood. ”

"For example, Yili is so scared and helpless now, just like a baby who can't walk is suddenly put on the ground by his parents."

Zhibai didn't know what she was doing on the front that Yili couldn't see, and it seemed that she was acting out what she said again.

Seeing that the endless black mist was about to take advantage of the weakness to cut through the two of them, Yili, who noticed that they were far away, hurriedly followed Zhibai.

As the two of them walked apart, a huge labyrinth shrouded in black mist came into view, but the towering walls were made up of bookshelves, and the gaps between the bookshelves reflected each other, making the labyrinth of books like a huge mechanism, standing abruptly on the grass.

Shocked by the building, Yili felt fear.

He stopped, and didn't follow Zhibai to the depths of the labyrinth.

Zhibai, who quickly sensed that something was wrong, also stopped and looked at Yili, who was retreating, and said, "Don't be afraid, it's safe here, and it won't hurt you." ”

"But...... It always gives me a sense of unease. After hesitating for a long time, the uneasiness that was about to erupt in his heart still drove Yili to choose to confess to him.

Zhibai Shu furrowed his brows and kept getting closer to Yili.

Just when Yili wondered what she was going to do, she decisively grabbed his hand and shook it, and said with a smile: "In this way, you won't be afraid, right?" ”

Yili faced her sincere eyes, and the idea of escaping came out of his head.

But before he could hesitate, Zhibai had already dragged him in. Yili simply gave up resistance and relaxed his heart to rely on Zhibai.

The labyrinth filled with black fog faintly exudes a terrifying aura. Zhibai seemed to be looking for something purposefully, and Yili looked left and right uneasily. Grey nameless books sit unevenly on the old-looking shelves, adding a touch of antiquity to the terrifying atmosphere.

Yili carefully observed, he figured out the direction of the bookshelves, observed the placement of the books, and a dejection gradually came to his mind—it was a circular labyrinth.

"As far as I know, the end of this labyrinth is in the center."

Zhibai had been guessing the way ahead through the gaps between the books, and soon noticed an out-of-place book on a bookshelf not far away.

On the shelves that were created in the last century, hundreds of books are overshadowed by the dust of history, and the dark tones make the colorful books look particularly conspicuous.

"Looks like this is it, will it be the story I want?"

"What?" Yili was puzzled by this.

"Nothing." Zhibai responded to him with a bright smile and opened the book. "Remember to find what you're looking for."

In an instant, the pages of the book flew, and the book lit up with a bright light, which made him can't help but close his eyes, leaving only the sound of the pages turning quickly in his ears loud, louder and louder, deafening, until Yili completely lost consciousness......

"The story begins."
